STM32F429IGT Read Configure & Frame from UVC Camera Failed

Hi all

My USB Camera support YUY2 & MJPEG format, PC read back the correct configuration, but STM32 not correct, the configuration only contain MJPEG format! And the other infomation seems correct. Why camera can distinguish the PC and STM32 host ?

I have attached the full configuration from PC & STM32, please have a look.

And even though I use the MJPEG to capture frame, evering is OK, but when I start a transfer, I can only receive SOF interrupt and 'USB_OTG_GINTSTS_PXFR_INCOMPISOOUT' interrupt, which mean 'Incomplete periodic transfer '. I don't why this happens, what should I do next.

Many thanks for your help!

hexdump.bin if from STM32, and USB_Capture_Camera_Addr_1.31.bin if from PC (captured by wireshark and copy the hex value).
